How to create a Makefile that sorts out lots of dependencies

Hi everybody,

My problem is that I can't compile the test class because the header it uses also uses several headers that again uses their headers etc.
the Library I'm working on is called ghmm (www.ghmm.org) the main directory for ghmm where the configuration etc is, is /ghmm/
Where the headers and their sources are locted is at /ghmm/ghmm/
The Test files are located, this is also where my files are stored /ghmm/tests/

Cheers
Idar

# asuming C or C++ source files:
gcc -MM list of your C-files >>Makefile

you can also use the -I option of GCC
-I./ -I../ -I<your header path 1> -I<your header path 2> -I<your header path n>


Here is a simple makefile

# Makefile for easy compilation.:-)

OPTIONS = -Wall -O2
INCLS = -I. -I../ -I<your list of path to headers>

CC = gcc
LD = ld
      
OBJS = $(wildcard *.o) #// you can also give list of .o  files

all: <your executable name>
.c.o:
      $(CC) -c $(OPTIONS) $(INCLS) $< -o $@

<your executable name>: $(OBJS)
      $(LD) -o <your executable name> $(OBJS)
clear:
      rm -f $(OBJS)
      rm -f *.c~ *~

regards

Hi guys, I solved it here, my problem was that the link did now know where to look

Solved:
test.c
     gcc -o output.run test.o -lstdc++ ../ghmm/.libs/libghmm.a -lm -lpthread

test.o: test.c
   gcc -c test.o output.run -I..   (the class must then help the make file find the library by ie #include <ghmm/sequences.h>
 

clean:
       rm test.o output.run

thanks though, Manish you were closest to my final solution - thanks
